Abstract:
This study examined how three non-optimal driving states - mind-wandering, distraction, and fatigue - differentially affect driving behaviour and psychophysiological responses from an arousal-resource regulation perspective. Thirty-licenced drivers completed repeated simulated driving tasks, during which behavioural performance and physiological indicators were recorded. Distinct state-specific profiles emerged. Distraction was associated with elevated heart rate and pupil diameter, accompanied by frequent and unstable control adjustments, reflecting a high-arousal, high-load control mode. Fatigue was characterised by reduced heart rate and eyelid opening, prolonged response times, and diminished operational activity, indicating hypoarousal and inhibited control. Mind-wandering showed an intermediate pattern, with moderate physiological activation but unstable behavioural rhythms, suggesting reduced task engagement rather than extreme arousal modulation. These findings indicate that attentional disruptions impair driving stability through distinct arousal- and resource-related mechanisms. The integration of behavioural and physiological measures supports a multimodal approach to driver state assessment.

M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
